我们在加工10马力锅驼机机体时,曲轴轴承盖的螺栓孔加工比较困难。螺栓孔的位置如图1所示。过去用小风钻钻孔,由于风钻力最小,时钻时停,一个工作班只能钻十几个孔,效率很低。钻好孔以后,还要用人工攻丝,由于空间小,操作也非常不方便,并且攻出的丝孔大部分不合乎要求。现在设计了一种钻具,使用这种钻具可以充分发挥钻床潜力。这种钻具装卸很方便,不必对钻床进行改装。使用这种钻具加工,生产效率比过去提高10倍以上,并且保
When we are processing 10 horsepower bullock machine body, the crankshaft bearing cap bolt hole processing more difficult. Bolt hole position shown in Figure 1. In the past with a small wind drilling, because the wind force is minimal, when the drill stop, a working class can only drill a dozen holes, the efficiency is very low. After drilling a good hole, but also with artificial tapping, due to small space, the operation is also very inconvenient, and most of the silk hole out of line with the requirements. Now designed a drilling tool, using this drill can fully exploit the drilling potential. This drill is very easy to handle, you do not have to modify the drilling machine. The use of this drill processing, production efficiency increased more than 10 times in the past, and Paul
